Usage
What does deception mean? Deception is the act or practice of deceiving—lying, misleading, or otherwise hiding or distorting the truth. The related word deceit often means the same thing. Deception doesn’t just involve lying. It can consist of misrepresenting or omitting the truth or more complicated cover-ups. Anything that involves intentionally misleading someone is deception. People can even engage in self-deception by avoiding the truth. The word deception often implies a pattern of behavior, rather than a one-time act. The adjective deceptive can describe something that deceives or is intended to deceive. A person who engages in deception can be described as deceitful. Less commonly, the word deception can refer to an action, scheme, or trick intended to deceive, as in It was a clever deception, but I didn’t fall for it. Example: I’m sick of your constant lying and deception—I can’t trust anything you say!

Etymology
Origin of deception
First recorded in 1400–50; late Middle English decepcioun, from Old French, from Late Latin dēceptiōn-, stem of dēceptiō “deceitfulness,” from Latin dēcept(us) “deceived” (past participle of dēcipere; see deceive) + -iō -ion
Explanation
Deception is a trick or scheme used to get what you want, like the deception you used to get your sister to agree to do all your chores for a month. Deception occurs when you deceive, a word that comes from the Latin de- meaning "from" and capere, meaning "to take." When you deceive someone, the result may be taking — like items you don't really need from people willing to give them, believing they are helping you. You may have heard the phrase "take someone for a ride." That's a way of describing deception.
